To all whom 'it may concern.' y

Re it known that i, ''havan /"i, lioivarixm a citizen oi the United States, and a resident oi lloloiado fiiprings, in the county oi" 'El Paso and State oi" Colorado, have invented a nen' and useiul ririune Heat Equipment Afor the Home, oli' which the tollmving is a specification.

My invention relates to devices Yfor the generation and'utiiization o heat and has for its major object, the provision ot single unit having facilities, tor heating the premises, for cooking, and (3) for heating Water :tor domestic use. Other objects will appear as the description progres? Although I have shown the preterreiil torni oit my invention in the accompanying drawings and recommend its use, yet l1 do not limit inyselii to the precise form as herein shown, but Wish it understcuiid that va.-A rious adaptions and minor details of? construction may be made Within the scope oit what hereinafter is claimed7 Without departing 'from the spirit of the invention.

Figure i represents a front eievation of the invention; Figure 27 a plan vie\vy partly broken away, (one portion being brolren along the line B-C Figure 3 Figure f3, a vertical section on the line A ot Figure 2, (partly broken away) 5 and Figure 4i.A a vertical section through the center oilE the inventioin (partly brokeny aivay).

Similar reference characters reifer to lilre parts tlfiroughout the several views.

The side .valls 10 and l?, the rear Wall L and the top wall 2G are constructed hollow7 as indicated in the draivinfrs, each wail comprising a separate Water chamber (10, 1T, l, and 26 respectively) said chambers being connected in a manner to provide a unique circulation system the purposes et which are hereinafter disclosed. fiaid'ivalls, together with iront ivall 3l, comprise. a chamber` in which is disposed the rectangula parti'nents) Vin snch position that channels 50, 50@ and 50 are formed.

A coil` l2, disposed. upwardly vi'ithin water chamber l and extending therefrom into Water chamber 10a, is connected with the household water supply by valve-controlled pipe '13 and with the domestic hot water system by valve-controlled pipe l5.

539 and 40 are grids supported on cleats lil., which divide box B into cooking compart ments 3d and 2345*; 4t2, Fume outlet pipe; L37

box i3, (coniprising the cooking com- 1413, horizontally swinging main doors, having therein transparent Windows 45, and supiiorted on hinges lei-444% 46, verticallyswinging auxiliary doors, having notches in the upper ends thereof, hinged in the lovver parts of said main doors; iii', verticallymoving slides in said main doors adapted to fit into said notches; 48, vhorizontallyswinging bar pivoted on the top of hinge 44a; 49, vertically-swinging door hinged to bar 48; and 3T, grids disposed on cleats 88 on extensions 35.

Valve-controlled pipe 20, a pop-off 21 and Water gauge 23 are mounted on side Wall 17, and valve-controlled pipe 56 is mounted on side wall 10, for purposes hereinafter explained.

Horizontal conduit 5, having damper G therein. extends thru back Wall l and opens into exit conduit 4f.

Dampers 53 and 53a, are hung Within channels and 50a.

The front Wall of Water chamber lfL comprises a series of vertical grooves. insulation Wall, 77 extending across the ends of said water chamber7 is disposed in front Voit said grooves, thereby forming downwardly-extending fines 2, having open conn munication above with channels 50, 50 and 5()b and below with exit conduit 4. (The major 'function of Wall 7 is to insulate water chamber la from the combustion devices and from compartments 34 and 34e.)

Water chamber lf2 having a Valve-controlled inlet pipe at its base7 has open commnnication at the top with Water chamber' 267 through nipple 3, and is connected at its extreme front7 with Water chambers 10EL and 1T respectively by nipples 28 and 18 (the latter having therein a valve 19) Water chambers l0 and 1.7 have separate communication with the radiator system via pipes l] and 24.v (having therein central valve 30) respectively.

My invention. which may be adapted to burn gas, oil, coal or other fuel, operates as follows:

The gases of combustion pass upward through channels 50 and 50a, backward through channel 530"7 downward through vdues 2, and into exit conduit 4. By opening damper @the gases may be passed directly from channel 50h.. via conduit 5, int-o exit conduit 4f..

The Water in a closed-cycle heating system is maintained under relatively lon7 and conf stant pressure, while a device which provides a continuous supply ot hot water for domestic purposes requires an intake port in open communication with .the water main wherein the pressure constantly liuctuates. The water circulating in myheating system and the water to be heated for domestic purposes are therefore maintained separately.

rThe return water 'from the radiator system enters water chamber 1a through valve.

controlled pipe 1b, Hows upward therein and through nipple 3 into water chamber 26a, thence iows forward therein and passes through nipples 28 and 18 into water chambers 10a and 17a. The movement ot the water, from its entrance into water chamber 1' to its exit from water chamber 26, is thus counter to the movement of the gases of combustion through channel 50h and flues 2. The water finally passes from chambers 1()a and 17, through pipes 11 and 24., again into the radiator system.

The water heated in coil 12, for domestic purposes does not receive heat direct from the gases of combustion, but from the water `in chambers 1a and 10a. The movement ot the water through coil 12, .is upward and therefore counter to the movement of the leases of combustion. l thus provide means by which two bodies of water are caused to flow counter to the gases ot combustion and are heated by a single device.

When the heating` system is not needed, hot water for domestic purposes may be derived (via pipe 5G) from water chamber 10, by closing` communication between said chamber and the radiator system (by means of valve 57) and between coil 12 and the water mains (by means of valve 14,) and then opening communication between the mains and water chamber 1a, (by means of pipe 58 and valve 58a).

)Vater chamber 17" is convertible into a low pressure steam generator, by closing valve 19 (thereby stopping' the inflow ot water from chamber 26a) 4and valve 3() (thereby stopping; the outflow into the radiator system). The water thus trapped in 17a may be heated to the required temperature, (regulated by pop-oil' 21) and. when valve 22 in pipe 20 is opened, steam may be trapped in a suitable drum (not shown). This implies that the walls of 17'rl be construeted to withstand the pressure.

Rectangular box B, (disposed, as hereihbetore described, in the chamber termed by walls 1, 10, 1T. 26 and 31) comprises the Cookino;Y element ot my invention. The bottom oF this box, which is divided into compartments 34 and 311 by `efrids 29 and 40, rests directly above the hre and is therefore analagous to the top of a cook stove or range, while compartment 341a comprises the bake oven; Horizontal bar 418, supporting` door a9, is hinged to swing outward, thus per mitting the opening `oit the entire front of the cooking` element. Main doors 13 and 13a (having therein transparent windows 1-5) contain auxiliary doors 16, which permit the insertion ot small cooking utensils, the bandles ot which may project thru the notches in doors ab. Pipe 42, communicating` between the cooking members and exit conduit t, permits the cooking;` ot onions, cabbage and other edibles which emit more or less offensive odors, without disagreeable conscquences.

.Grids 36 and d'7, one of which is movable, are adapted to regulate the area of the bottom of box B directly exposed to the tire, and therefore the temperature in cooking compartments 341 and 34H. Swinging dampers 53 and 53a are also adapted to regulate the temperature in the cooking compartments; the ascending gases of combustion being` dellected to ror from the walls or" said compartments, by swinging .these dampers inward or outward.
